HEIF Image Container Format Leverages H.265/HEVC to Store Photos and Image Sequences

A few years ago, Google introduced WebP image format leveraging VP8 video codec, and the Moving Picture Experts Group (MPEG) has decided to do something similar but instead of using VP8, they went with their own H.265/HEVC video codec for HEIF image container format.

HEIF stands for High Efficiency Image File, and is defined by ISO/IEC 23008-12 (MPEG-H Part 12). The storage of the data is based on ISO Base Media File Format (ISOBMFF), and HEIF appears to be especially useful to replace animated GIFs file with better quality and much lower sizes, as well as burst photos.

HEIF also appears to compress a little better than JPEG photo with similar quality, but HEIF appears to fallback to JPEG codec sometimes, so it may be improvement in the way metadata is handled? The comparison table show the different features between HEIF and other well-known image format (JEG, WebP, GIF, etc…). Source: Nokiatech Github.io page.

I had no idea you could embed audio into JPEG files until today.

HEIF files normally use .heic or .heif extension, and support has been implemented in macOS High Sierra and iOS 11, and it’s coming to Android P and Windows 10 Build 17123. Nokia has also released an open source JavaScript HEIF writer/reader with the code available on Github.
